Explanation:
The hard, solid material that forms part of the surface of the earth are called rocks. The three main types, or classes, of rock are sedimentary, metamorphic, and igneous and the differences among them have to do with how they are formed. Sedimentary rocks are formed from particles of sand, shells, pebbles, and other fragments of material. Together, all these particles are called sediment.
Answer:
there are three types of rocks -
(1) igneous rocks-the liquid form of molten rocks in the interior of earth is called magma . when molten magma cools solidifies and crystallizes inside the earth's crust or on the earth's surface ,igneous rocks are formed.
(2)sedimentary rocks-rocks roll down hit each other and crack and they are broken down into small fragments .Weathering is long process of breaking up of rocks. Erosion is the wearing away of the rocks by water, wind and ice .This eroded material is the transported and deposited in layers by wind water etc. These deposit are called sediments .
(3)metamorphic rocks -Metamorphic means change in form or nature igneous and sedimentary rocks can change into Metamorphic top under great heat and pressure without melting often if insert the earth the process of chain itself is called metepar is the he does not melt The Rock but bring about there in the structure for example Renault change into sale chocolate change into splayed and plant stone into marble 728 into court judge
